Subject: On Ubuntu 16: After sucessfull SSH connection established; X2Go session does not start

Date: Mon, 28 Nov 2016 20:24:06 +0100

Package: x2goserver
Version: 4.0.5.1
Severity: grave

Version client side: x2goclient 4.0.5.1 on Ubuntu 16 XFCE+ssh server
Version server side: x2goversion delivers 4.0.1.20 on Ubuntu 16 
XFCE desktop

After a fresh installation of x2go on the server and client side without 
special settings or problems I try to just get an xterm. I have the 
following severe problem:

Running x2goclient with --debug shows sucesfull SSH connection 
established. But after this the exec channel closes with "Have stderr 
only, something must be wrong."

In the GUI a message "Cannot open display "default display"" shows up

The message SSH finished: raw output (stdout): "setxkbmap -option 
ctrl:nocaps" could be a hint that some error processing during login 
does not work ??

Any idea how to debug ??

I attached the whole log

best regards

Stefan Auracher

[Message part 1 (text/plain, inline)]

Hi,

1) Are you trying to connect as "root"?
   If so, you should absolutely not do this.  Always use a regular user
   account and su or sudo afterwards.

2) Are you using a different default shell than /bin/bash?

3) Are you using some kind of central authentication (LDAP, AD) and/or
   a non-local /home directory, like, say, a NFS mount?

4) What happens when you try to log in using a newly created user with
   an "empty" home directory on the server?

5) Is there anything non-standard in

  /etc/profile.d/*
  /etc/profile
  /etc/bash.bashrc
  ~/.profile
  ~/.bashrc

(For example, /root/.profile contains "mesg n" at its end, by default,
while regular user accounts don't have that in their ~/.profile.  This
causes error messages - though usually different ones than the one you
reported - when trying to connect as root, and results in a failed
connection.  Something similar might be going on here.)

Kind Regards,
Stefan

Subject: Bug 1116 solved

Date: Tue, 29 Nov 2016 15:41:26 +0100

Package: x2goserver
Version: 4.0.5.1
Severity: grave

The problem was similar to bug 1091
I solved it by removing the command setxkbmap from my .profile
The error handling should be improved. The error message
"Unable to open display" is here confusing. Better would be something like "got output on stderr during login therefor exit"

Thanks a lot: I installed x2go now the first time and it is running on Ubuntu 16 server + client; both with xfce

I still have problems with sound forwarding

Note that you don't have to remove it completely; wrapping it in a check
like

if test -t 0; then
	your-command-here
fi

should do. This test will only return true if you're runniny a TTY
session, which X2Go does not.

May I suggest you subscribe to x2go-user as well, ask your questions
there, and open a new bug if it turns out to be an actual bug and not
user error?

Kind Regards,

For commands expecting a TTY (e.g. "mesg"), yes. setxkbmap should not be wrapped
into this, but rather $DISPLAY checked for existence *and* its stderr messages
redirected either to a file or to /dev/null. In reality, this call doesn't
belong in ~/.profile at all, but I'll leave that to the user to sort it out...


Closing up.
